Patent

CA 2117523

A process for isoparaffin-olefin alkylation is provided that permits the use of solid catalysts which require frequent regeneration and high isoparaffin/olefin ratios. The process comprises circulating in a reactor (10) a slurry comprising: solid acid zeolite catalyst particles (20-2000 microns) from hopper (50) and recirculating slurry (20) and feed (70) of liquid reactants comprising isoparaffins and olefins in an isoparaffin to olefin molar ratio of less than 100, recycling a first portion (20) of said slurry to provide an isoparaffin to olefin molar ratio in the reactor of at least 500, passing a second portion of the slurry to a separating means (30) to separate alkylate product (32) from said solid catalyst particles in a separation means (34) and regenerating the catalyst particles in a regeneration means (36).
